Cold Dark Matter and Self-Interacting Dark Matter Interpretations of Cloud-9
Morgan Ohana, Xingyu Zhang, Hai-Bo Yu
Recently, the Five-hundred-meter Aperture Spherical Telescope discovered a gas-rich hydrogen cloud near M94 in the band. Lacking an optical counterpart, this object,…
SIDM and CDM interpretations of the million-solar-mass lensing perturber JVAS B1938+666-
Xingyu Zhang, Hai-Bo Yu
A object has recently been inferred from gravitational imaging of the strong-lensing system JVAS B1938+666, exhibiting an unusually dense inner region embedded with…
Dark Bondi Accretion Aided by Baryons and the Origin of JWST Little Red Dots
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
The gravothermal core collapse of self-interacting dark matter halos provides a mechanism for seeding supermassive black holes in the early Universe. We show that the collapse of a…
Probing Signals of Self-Interacting Dark Matter Core Collapse in HI-Rich Galaxies
Demao Kong, Hai-Bo Yu
We analyze rotation curves of five HI-rich galaxies recently discovered with MeerKAT. These galaxies exhibit sharply rising rotation curves, while their baryonic components are not…
The GD-1 stellar stream perturber as a core-collapsed self-interacting dark matter halo
Xingyu Zhang, Hai-Bo Yu, Daneng Yang +1
The GD-1 stellar stream exhibits spur and gap structures that may result from a close encounter with a dense substructure. When interpreted as a dark matter subhalo, the perturber…
CDM and SIDM Interpretations of the Strong Gravitational Lensing Object JWST-ER1
Demao Kong, Daneng Yang, Hai-Bo Yu
van Dokkum et al. (arXiv:2309.07969) reported the discovery of JWST-ER1, a strong lensing object at redshift , using data from the James Webb Space Telescope. The lens m…
Self-interacting dark matter interpretation of Crater II
Xingyu Zhang, Hai-Bo Yu, Daneng Yang +1
The satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold da…
